David Crosby, the lead singer for Crosby, Stills and Nash., became one of the most successful rock musicians of all time. But even at nearly 80 years old, Crosby could not stop hitting the road and promoting his music. He was worth over $40 million. And his wife did not want him to travel, but his entire sense of significance was wrapped in his music.

In a film about his life, Crosby expressed a lot of regrets. “People ask me if I got regrets,” he said. “Yeah, I got a huge regret about the time I wasted being smashed. I'm afraid. I'm afraid of dying. And I'm close. And I don't like it. I'd like to have more time—a lot more time.”

Crosby tells his interviewer that music “is the only thing I can contribute, the only thing I got to offer.” Then toward the end of the film, he raises the volume of his voice and the intensity of his delivery with these summarizing words: “The one thing I can do is make music. Myself. So, I'm trying really hard to do that.” His interviewer asks, “To prove yourself?” Crosby responds, “That I'm worth a [expletive].”
